STON E-WAGON.

SPECIFICA'JTION forming part of Letters Patent No. 555,673, dated March3, 1896.

Application filed March 18, 1895. Serial No. 542,122. (No model.)

, following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

The present invention relates to vehicles and is embodied in an improvedvehicle intended especially for hauling stone, lumber, &c., in thecountry where facilities for loading and unloading are not readilyaccessible.

The apparatus embodying the present invention combines the advantages infacility of loading and unloading of the ordinary drag withthose of awheeled vehicle in transmission when loaded. To attain these ends atruck is provided mounted upon wheels in the ordinary Way, preferablyhaving the front axle readily detachable therefrom for a purpose to behereinafter described. A detachable carrier for the load is alsoprovided consistin g of a flat platform which can be placed upon theground so that the stone or whatever is to be carried can easily berolled upon it, and means are provided for attaching the said platformto the truck and hoisting the same from the ground so that it issuspended therefrom and thus becomes a part of the vehicle. Thus thecarrier can be placed on the ground near the material which is to bemoved, the material being placed thereon substantially without beinglifted from the ground and the truck then brought up into position overthe carrier, the main portion of the truck being, if desired, brought upseparately from the front axles thereof, and after the truck is in placethe carrier is attached thereto and hoisted from the ground.

Figure 1 is a sectional elevation of the apparatus, and Fig. 2 a topplan view thereof.

As herein shown the truck is constructed in the form of an openframework having longitudinal side portions a, mounted at their endsupon the cross-bars a the said cross-bars being supported respectivelyupon the rear and front axles, a and a, the latter being secured by theking-pin a Fig. l, in the ordinary way. To support the load a carrier1), consisting of a flat platform, is suspended from the truck by meansof chains or cables 19 the said chains preferably being readilydetachable from the said platform as byhooks b co-operating with staplesin the said platform, as shown.

WVhen it is desired to moveaload of stone, for example, the carrier 1)is placed upon the ground as near as possible to the stone and the stonethen rolled or pried thereon, after which the truck is brought up intoposition over the said carrier, the front axle and the main portion ofthe truck being, if desired, brought up separately in order tofacilitate the positioning of the truck directly over the load, and thecables 12 are then secured to the ends of the carrier. In order to hoistthe carrier from the ground, after it is thus secured to the truck, thecables 6 are connected to windlasses 0, one at each end of the truck,and the said windlasses are provided with leverarms 0 radial to theiraxes, for turning said windlasses and winding the cables 79 thereon,thus hoisting the carrier and its load from the ground. The levers c arepreferably detachable from the windlasses and, as shown herein, aresimply thrust endwise into holes 0 in the periphery of hubs 0 upon saidwindasses.

In order to facilitate the operation of hoistin g the load, thewindlasses are each provided with a ratchet-surface c and pawls c",which serve to prevent the cables from unwinding when during thehoisting operation it is necessary to transfer a lever from one of theholes to another. After the load is hoisted, however, it is preferablysupported by the lever itself engaging with a portion of the truck, suchas a cross-bar a, thus relieving the pawl of the strain.

As shown herein the rear double Windlass is transversely mounted inbearings upon the side portions a, and is provided with two chains, onefor each of the rear corners of the carrier. The front Windlass on theother hand extends longitudinally from the front crossbar, a to anadditional cross-bar, a parallel thereto, and is provided with only onechain attached to the center of the front portion of the carrier.

It will be observed that by arranging the front Windlass longitudinallyof the truck it may be conveniently operated from the side of the truck,no matter where the power be applied, and thus the operator will not beobstructed by the draft-gear and draft animals. It will also be observedthat by arranging the front Windlass longitudinally of the truck, I amenabled to use a single chain, and the chain in winding and travelingupon the windlass will retain its center of gravity longitudinally withrelation to the platform or carrier and thereby prevent the carrier fromswinging transversely, and thus preserving the position of the carrierwith relation to the truck in hoisting.

The windlasses are preferably supported in open bearing-pockets c therebeing no need of an upper bearing-surface since the weight of the loadwill be sufficient to hold them seated when in use. The whole apparatusmay be simply and inexpensively constructed, and by its operationgreatly facilitates the transportation of stone, lumber, &c., which isnow commonly either loaded with great diiiiculty upon wheeled Vehiclesor transported upon drags which require great hauling power to movethem. It is obvious, moreover, that the operation of unloading is asmuch si1nplified by the use of this apparatus as that of loading.

I claim-- The combination of a truck mounted upon axles and detachablysecured to one of said axles as by a king-pin, a double Windlassarranged transversely of the truck at the rear thereof and carrying twochains, a windlass arranged longitudinally of the truck at the frontthereof and carrying a single chain, a carrier consisting of a separateplatform adapted to be detachably connected to said chains, andindependent means for operating said windlasses, substantially asdescribed.

In testimony whereof I have signed my 40 name to this specification inthe presence of two subscribing witnesses.
